缩微过程

A microcosm system was used in laboratory to study the decomposition of mixed foliar litters from Cunninghamia lanceolata and,either Michelia macclurei var.sublanea,Castanopsis hystrix or Schima superba to explore the possible interaction between various species litters during their decomposition.

采用缩微实验法，初步系统研究了杉木叶凋落物分别与火力楠、红栲和木荷 3个阔叶树种之一的叶凋落物两两混合分解的动态变化，以探明凋落物混合分解过程中可能存在的相互作用。

The fracture reasons of high strength PC steel wire are analyzed, it's considered that center segregation, central cavitation, poriness and inclusion are the metallurgical reasons which lead to the facture of PC steel wire and in the rolling process, differential coping quality, microcrack caused by surface defect, abnormal microstructure caused by burnt and improper cooling velocity, the ears on the head of the wire, overlapping of the wire rod itself are the main reasons which lead to the facture of PC steel wire. At the same time, inappropriate pickling, differential phosphorization quality, the bad heat treatment quality, the generation of crack in the improper drawing and transverse crack caused by abnormal laying of the drawing die are also the reasons of the cracking of PC wire.

对高强度PC钢丝断裂原因进行了分析，认为连铸坯的中心偏析、中心缩孔、疏松和夹杂是导致PC钢丝断裂的冶金原因；轧制过程中，较差的修磨质量、表面缺陷导致的微裂纹，过烧以及不适当的冷却速度导致的非正常显微组织，盘条头部的耳子、盘条本身折叠是导致PC钢丝断裂的主要原因；同时，不恰当的酸洗、较差的磷化及热处理质量、不适当拉丝裂纹的产生、拉拔模具安放不正导致的横裂也是PC钢丝断裂的原因。

Adding a small quantity of three functional group of polyvalent can improve the water resistance and decoration of copolymer emulsion after film forming. The structure form of interpenetrating networks has a greater destroy degree to the micro crystal of polyurethane film forming substance than the effect of the prepolymer capping graft copolymer.IV, This article studies on the heat stability of acrylate modified polyurethane dispersion, researches the changes of the structure of acrylate modified polyurethane dispersion afterheating, and analyses by the heat analysis, infrared ray and heat analysis, and mass spectrometery.

利用拉曼光谱和扫描电镜、红外光谱等测试技术，分析了丙烯酸酷及丙烯酸酷一有机硅等改性聚氨酷水分散体的成膜过程—利用预聚体封端技术合成的丙烯酸酷改性聚醚聚氨酷的成膜过程包括乳液颗粒的挤压成膜与分子硬段的微区结晶，有机硅氧烷的引入将同时出现硅氧烷的水解缩合；具有互穿网络结构的丙烯酸酷改性聚氨酷水分散体因丙烯酸酷的互穿而限制了聚氨酷硬段在成膜过程中的结晶，聚合物成膜以挤压成膜为主，有机硅的复合改性同样出现硅氧烷水解缩合现象。8。

Lipid scrambling in resealed ghosts occurs in the absence of cell shrinkage and microvesicle formation, processes that are generally attributed to Ca(2+)-induced lipid scrambling in intact erythrocytes.

重封血影细胞中的脂质紊乱在细胞皱缩缺失和微泡形成时发生，此过程在完整的红细胞中通常归因于Ca(2+)诱导的脂质紊乱。

This one mode pays close attention to network credence foundation of the businessman very much.
